Number magic: not actually magic
A thing I’ve seen around the internet is “if you add your age to the last two digits of your birth year, it is 111! magic!” – I’ve tried explaining why this isn’t magic, but haven’t made it as simple and clear as nbisby on the opera blog. To paraphrase:
- Consider your age is (2011 – yearborn)
- The last two digits of your birth year is (yearborn – 1900)
- Added together is (2011 – yearborn) + (yearborn – 1900)
- The year you were born cancels out:
- 2011 – 1900 = 111
The magic where you have a ring of numbers, and no matter where you start the instructions always have you finish in the same place, use similar cancelling-itself-out tricks :3
